PATENT OFFICE GEORGE R. WARD, OF' NEW YORK, N. Y., ASSiGNOR To CHARLES F. OOBURN, O131 BOSTON, MASSACHUSETTS.

PAoKAomG-MACHINE.

SPECIFICATION Aformingpart of Letters Patent No. 741,748,`dated October 20, 1903.

Appnonot met August 6, 1to1.; Semi 110.71.014. (Nomad.)

Beit known that I, GEORGE R. WARD, a citizen of the United States, residing at New York, N. Y., have invented`certain new and usefullmprovements in Packaging-Machines, of which the following is a clear,full, and exact description.

My invention relates to a packaging-machine; and my object is to construct a machinewhich will be automatic, simple, speedy,

and accurate.

In the present embodiment shown inthe drawings I have provided a vertically-rotating carrier whichhas a'plurality of radiallydisposed pockets'. Theipackage may bea bag formed outside the machineand automatically inserted in one of the pockets. The c arrier is then rotated to bring the pocket and package into an upright position, where it is filled. Theendapsarethen foldeddownand the carrier rotated and the bag discharged.

My invention will be pointed out in the claims.

In thepreferred embodiment of my invention shown in the drawings, Figure lis a side elevation; Fig. 2, a top plan View; Fig. 3, a front elevation, parts being removed. Figs. 4 to 13 show details. Figs. 14 to 19 are diagrammatic views showing the different steps in forming the bag. 'Figsj20`to 2 4'show details.' Figs. 25 to 28 show details of mechanism for forming the bag before'the bottom of the bag is formed. Figs. 29 and 30 are respectively side and front detail views of mechanism for folding in the end laps of the bag to form the bottom. Figs. 31 to 33 are details of the mechanism for inserting the bag into a pocket in the carrier. Figs. 34 to 38 show detail viewsof cams and levcrs'actuated thereby for operating different parts, as hereinafter explained. Figs. 39 and 42 are detail views of the carrier in longitudinal and tiansverse vertical sections, respectively; and Figs. 40, 41, and 43 are details lofthe mechanism for folding in the end [iaps of the bag after it has been filled. l

In the above preferred embodiment the strip of paper l from the roll 2 is drawn between rolls 3 4, rotated as indicated in Fig. 1. These rolls are shown enlarged in Fig. 4 in elevation and in Atop plan in 5.

`5, with which this dog 9 may engage.

19 through suitable gearing.

large enough to form a bag. through aguideway 27,Figs. 20 and 2l,formed shown,-ready to be formed into a bag.

These rolls are intermittently given one full turn to feed forward and partially separate a piece of the paper strip sufficiently large to form a bag. The lower roll 4 is xed to a 55 shaft 5, and rotatable on this shaft is a gearwheel 6, having a cylindrical portion 7, Fig. 7, on which is fixed a disk 8, to which is pivoted a dog 9. A disk 10, having a ratchetshoulder 11, Fig. 6,'is xed on the lower roll 6o A reciprocating rack 12 slides in a guideway 13 and engages gear-wheel 6. This rack is reciprooated by a lever'l-i, Figs. 1 and 2, pivoted on shaft 15 and carrying a roller 16, which, Fig. 65 34, engages acam-groove'l' inthe perpendicular face of a wheel 18, rotated by driving-wheel The upper roll 3 is fixed to shaft 20, Fig. 4, and a gear-wheel 2l on shaft 2O engages with a similar gear 7o (not shown) on shaft 5. Roll 4 has a depression in its face into which a knife 22 on the upper roll enters to partially separate a piece of the paper strip, as shownin Fig. 21. When lthe rack 12 is drawn downward, the rolls are 75 not rotated, .as the gear-wheel 6, disk 8, and

glution, whichl will push forward and partially 8o separate' a portion 23 24 25 26, Fig. 2l, just The strip is fed of a strip of metal having its sides turned over, as shown in Fig. 20, into position 25, as 85 The bag is preferably formed byfolding it around a shell-form 28, located above the strip, Fig. 25, which is a view from the rear.4 This shell 'slides ton a fixed squared portion 29, extend- .9o l ing forwardly from a cross-piece 30, Figs. 2

and 1l, on the frame of the machine. vViithvin a fixed portion 3l, Figs. 25 and 29, slides y a sleeve 32, .and within this sleeve a plunger 133 reciprocates, carrying ahead 34, Fig. 25, 95

rocked byacam-groove 39 on wheel 40, Figs.

29 and 35, in which groove is ller 41,car

ried on lever 35. When the portion 23 26 has reached the position shown in Fig. 21, the cam 39 raises the lever 35 and plunger 33, pressing the strip between the head 34 and lower portion of shell 2S. In order to fold the sides of the bag-strip up into the form shown in Fig. 15 and in dotted lines in Fig. 25, I have in this embodiment provided a pair of wings 42 42, pivoted on shafts 71 71, passing through lugs 43 43 on head 34 and normally thrown down by springs 72 72, as shown in Figs. 12 and 25. The sleeve 32, Fig. 29, carries at its upper end a pair of upwardly-projecting arms 44 44, Fig. 25, which when the sleeve is raised into the position shown in Fig. 29 will turn the wings on their pivots into the vertical position shown in said latter figure, thus folding the strip into the form shown in Fig. 15. This sleeve 32 is raised by means of a cam-groove 45 on wheel 40, Fig. 35, in which groove runs a roller, carried on lever 46, Figs. 25 and 29, which lever carries a pin 47, engaging slot 48 in a head on the lower end of the sleeve. The upright sides of the strip are folded down on top of the shell 2S bytwo laterally-reciprocating folders 50 51, Figs. 2, 25, 26, and 27. Folder 50 passes Linder a paste-pot 52 and receives a small quantity of paste on its upper surface from an automatic feed-brush 53 in the bottom of the pot. As the folder 50 slides to the right in Figs. 26 and 27 it folds down one side, and folder 51 then slides out and folds the other side of the strip down upon it, as shown in Figs. 26 and 27, thus receiving paste from the folder 50 and sticking the two sides together when folder 50 is withdrawn. The folder 51 may be made in the form of a spring, as shown, to also press the overlapping edges together. This operation forms the strip into the tube shown in Fig. 16. The folders slide in guideways 54, Fig. 2, and are actuated by levers 55 56, Fig. 3, carrying rollers which engage cam-grooves 57 58 on the faces of wheels 1S 59. The bagis preferably formed by then folding in the end of the tube which projects beyond the shell, as shown in Fig. 16, to form the bag-bottom. A plate 60, Figs. 1, 29, and 30, pivoted on an arm 6l, which is xed to a rock-shaft 62, contacts with a brush 64 in paste-pot 65 and is reciprocated by means of cam-grooves 66, Fig. 1, in wheel 59 through a rolleron rock-lever 67, link 68, and arm 69, also fixed to rock-shaft 62. The plate 60 is thrown down into the position shown in Figs. 29 and 30, carrying a quantity of paste, and folds one Hap down, asshown iu Fig. 17. The plate remainsin this position until the other flaps are folded upon it, as hereinafter described. Thin folders 70, Figs. 29 and 30, pivoted on rock-shafts 71 71, Fig. 12, are located at the forward end of shell 2S. Fixed to these folders 70 are pinions 73 73, with which engage reciprocating racks 74 74, Fig. 30. XVhen the racks are pushed upward, the folders 70 are thrown inward and the side flaps are by them folded in, as shown in Fig. 18, against the exposed face of plate 60, which carries the paste. The racks 74 are reciprocated bya cam-groove 75 (shown in dotted lines in Fig. 36) in wheel 76, in which groove runs a roller on rock-lever 77, Fig. 29, which has an upward extension 78, carrying a slotted lateral extension 79, Figs. 25, 29, and 30, in which shaft 80, to which the racks 74 are fixed, is located. The racks slide in suitable guideways, as shown. The remaining triangular Iiap of Fig. 18 is folded up against the other iiaps and against the paste-covered face of plate 60 by a sliding plate 81, Figs. 29 and 30, pivoted to a lateral extension 82, Fig. 25, on upright portion 83, carried on rock-lever S4, which lever carries a roller located in cam-grcove 85 in wheel 76, Fig. 36. When this plate 81 is pushed upward, it folds the remaining flap up and through spring S6, Fig. 29, presses the flaps against the pastecovered face of plate GO, which being then withdrawn leaves the bottom aps securely pasted and pressed together to form the bagbottom, as shown in Fig. 19. This completes the bag. I am aware that bags or packages may be formed in other ways or by other mechanism, and I therefore do not limit myself to the bag shown nor to the mechanisms above described. The bag is then inserted into a carrier. This carrier 87 is shown in Figs. 22, 23, 39, and 42 and preferably rotates in a vertical plane and has a plurality of pockets, in the present embodiment disposed radially of the axis of rotation, to receive the empty bags. The carrier may be pivoted on trunnions S8 8S, turning in bushings 89, fixed in the frame of the machine. rl`he carrier being in the position shown in Fig. 39, the bag is inserted into pocket 90, as follows: A plunger 91, carryinga head 92, reciprocates within the fixed extension 29, Figs. 11 and 12, and contacts with the inside ot' the bag-bottom and pushes the bag to the left into the pocket 90. If the plunger 91 were alone used to acccomplish this, it would probably pull apart the newly-pasted bottom aps of the bag, and I therefore move the shell 2S, along with .the plunger, from the position shown in full lines in Fig. 11 to that shown in dotted lines. The bag is thus carried along bodily without danger of having the bottom flaps separated.

93 is a reciprocating bottom for the pocket 90, which contacts with the outside of the bottom of the bag. I preferably connect the bottom of one pocket with that of another one, so that when one moves in the other moves out, as will be described hereinafter. In the present embodiment the pockets are disposed in pairs opposite to each other, as shown in Fig. 39, and the connection may be a reciprocating rod 94. The bottom 93 being in the position shown in Fig. 11,when the bag is moved up to it the bag-bottom is pressed between the head 92 and bottom 93. The shell is then drawn backward, there boing IOC IIO

then no danger of separating the bottoni aps. The plunger 91 moves4 forward, however, pushing the bag into the pocket against the bottom 93 until the rod 94 has pushed the package in the opposite pocket (see Fig. 39) out of the pocket into the chute 95, as will be hereinafter described. The plunger 91 is then withdrawn, the bottom 93 having been forced inward tothe end of the pocket, as shown in Fig. 12.

The mechanism for moving the plunger and shell is as follows: Sliding in guideways in the frame are slides 96 97, Figs. 31 to 33. Fig. 33 shows a detailview from the rear. The shell 28 is connected to slide 96 by an eX- tension 98 and a cross-,arm 99, to which is pivoted a link 100, which at the other end is pivoted to a rock-lever 101, Fig. 36, carrying a roller located in a cam-groove in wheel102. Similarly plunger 91 is reciprocated by a camgroove in wheel 103, Figs. 1 and 35, in ywhich is located a roller on lever 104, connected to slide 97 by link 105 and cross-arm 106. The carrier is then rotated a quarter of a turn to bring the bag into an upright position ready to be filled, as shown in Fig. 39. The carrier is rotated by wheel 107, Fig. 22, which car-V ries a roller 1073, which engages and slides in slots in the carrier, as shown. The carrier is shown in Fig. 23 being rotated to its new position. A locking device to hold the carrier from moving is shown in Figs. `22 andl 23. This may be a pivoted. lever 108, having a lug l09,which engages each of the pockets in turn. It is pressed upward by spring 110. It is unlocked by means ofcam 111 on wheel 127 which strikes projection 113 on the lever and holds the lug out of engagement with the carrier until another pocket comes around.

The bag is filled in the upright position by a hopper 114 or otherwise, and in order to close the bag I have provided means to fold in the end portion, and I preferably use the following mechanism: A plate 115, Figs. 40, 41, and 43, is pivoted on a rock armV 116, which is rocked by a camgroove in wheel 117, Fig. 37. A spring 118, Fig. 43, normally presses plate 115 against the paste-brush 119. When arm 116 is thrown backward, a lug 120 strikes a part of the frame, as shown in dotted lines in Fig. 40, and plate 115 is thrown down to the position shown in Figs. 41 and 43, folding in one flap, as indicated in Fig. 17. The plate remains in this position until the other folds have been made. The sides arefolded in by rocking fingers 121, Fig. 43,v

pivoted to the frame, and normally thrown into the position shown in dotted lines in Fig. 43 by springs 122. The fingers have pins 123, which are struck by pins 124, projecting from arms 125 126, actuated by cam grooves in wheels 117 and 127, respectively, Figs. 37 and 38, and fold in the side flaps, as shown in Fig. 43. The remaining triangular fia-p is folded down on the paste-covered side of the plate 115 by a rounded rod 128, extending laterally from cran karm 129, pivotedin rock- `arm 130. This arm is actuated bya cam-z groove in wheel 127, as shown in Fig. 38. A;

lug 140 on arm 129 strikes projection 141 and throws down the folder 128 into theposition shown in Fig. 41 onto the paste on platell, and as the plate is then withdrawn the arm 130 by its movement farther forward causes folder 128 to press the pasted folds together.

The carrier then rotates another quarter-turn, f

carrying the bag into the horizontal position opposite its original place. Fig. 40, keeps the folds from separating as the end of the bag slides along it. As a new bag is inserted in a pocket the lled and pasted bag is expelled from its pocket by the bottom of the pocket moving outward.

Iam aware that many changes maybe made in the constructions herein set forth without departing frommy invention, and I therefore do not desire to be limited to the embodiments herein described and illustrated.
